Apparently, the embodiments to be described are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

First, it should be noted that a wireless handheld device described in the embodiments of the present invention includes but is not limited to electronic devices capable of sending a short message such as mobile phones of different systems, smart phones based on different operating systems, personal digital assistants PDA.

Various embodiments of the present invention are described with reference to details discussed in the following, and the various embodiments are shown in the accompanying drawings. The following descriptions and drawings are used to describe the present invention, and should not be construed as a limitation to the present invention. Many details are described so as to provide a thorough understanding for the embodiments of the present invention. However, in some examples, well known or regular details are not described, so as to provide a brief discussion about the embodiments of the present invention.

Some of detailed descriptions in the following are presented in the form of algorithms, and these algorithms include operations of data stored in a computer memory. An algorithm is generally an operation sequence for obtaining an expected result. These operations usually require or involve physical manipulations on physical quantities. Usually (though not necessary), these quantities are in the forms of electric or magnetic signals that can be stored, transmitted, combined, compared, and manipulated in another manner. It has been proved that sometimes it is convenient to mention these signals as bits, values, elements, symbols, characters, items, numbers, and so on, which is mainly for the purpose of universality.

However, all these and similar terms will be associated with appropriate physical quantities, and only apply to conveniently marking these quantities. Unless obviously specified in the following discussions, it is acknowledged in the entire specification that the discussion about a term such as “process”, “detect”, “match”, “start”, “close”, “unlock”, “enter”, “exit”, “set”, “pause”, “determine”, or “execute” may refer to an action or processing of a data processing system or a similar electronic device, and the data processing system or the electronic device manipulates data represented as physical (electronic) quantities in a register and a memory in the system, and converts the data to other data similarly represented as physical quantities in the memory or the register or other such information storage, transmission, or display devices in the system.

A touchscreen triggering method provided in an embodiment of the present invention is shown in FIG. 1, and the method includes the following.

S101: Detect an input combination that is of a click frequency and/or click intensity and is received when a touchscreen is in a locked state.

Herein, a processor or a corresponding module of a wireless handheld device detects an input combination that is of a click frequency and/or click intensity and is received when a touchscreen is in a locked state, which may be detecting an input combination that is of a click frequency and/or click intensity and is received at preset one or more positions when the touchscreen is in the locked state, or may be detecting an input combination that is of a click frequency and/or click intensity and is received at any one or more positions when the touchscreen is in the locked state.

It should be noted that the detecting an input combination that is of a click frequency and/or click intensity and is received when a touchscreen is in a locked state may be detecting a first click and a click frequency and/or click intensity of all clicks within preset time following the first click, and counting the detected first click and the detected click frequency and/or click intensity of the all clicks as one input combination of the click frequency and/or the click intensity, for example, if the preset time is 30 seconds, and 5 clicks are performed within 30 seconds following a first click on the touchscreen, a click frequency and/or click intensity of the 6 clicks is counted as one input combination of the click frequency and/or the click intensity.

S102: When it is detected that the input combination that is of the click frequency and/or the click intensity and is received when the touchscreen is in the locked state matches a pre-stored input combination of a click frequency and/or click intensity, where the pre-stored input combination of the click frequency and/or the click intensity is corresponding to an operation, execute the operation corresponding to the matched pre-stored input combination of the click frequency and/or the click intensity.

When the processor or the corresponding module of the wireless handheld device detects that the input combination that is of the click frequency and/or the click intensity and is received when the touchscreen is in the locked state matches a pre-stored input combination of a click frequency and/or click intensity, where the pre-stored input combination of the click frequency and/or the click intensity is corresponding to an operation, after unlocking the touchscreen, the processor or the corresponding module of the wireless handheld device starts a music player.

Herein, the pre-stored combination of the click frequency and/or click intensity may be a combination of a click frequency and/or a click intensity, where the combination of the click frequency and/or the click intensity is set and stored by a user and corresponding to a related operation, and may also be a combination of a click frequency and/or click intensity, where the combination of the click frequency and/or the click intensity is set and stored by a manufacturer of a wireless handheld device and corresponding to a related operation.

In addition, the operation corresponding to the input combination may include at least any one of the following, including starting one or more application programs, pausing one or more application programs, closing one or more application programs, starting one or more menus, closing one or more menus, unlocking a touchscreen, entering one or more function interfaces, exiting one or more function interfaces, setting a parameter of a mobile phone, setting a mode of a mobile phone, setting a function of a mobile phone, and so on. For example, for a certain input combination, it may be starting a music playing function, or pausing a music playing function, or closing a music playing function, starting or closing an alarm clock, starting a camera or a video camera, starting or closing a radio, starting or closing a network connection, and so on, may also be starting a setting menu of a mobile phone or closing a setting menu of a mobile phone, and so on, and may also be entering a network selection interface or exiting a network selection interface, where setting a parameter of a mobile phone is, for example, setting a volume, an incoming call ringtone, and a notification ringtone of the mobile phone, and so on, setting a mode of a mobile phone is, for example, setting a silent mode, an airplane mode, or a normal mode, and so on, and setting a function of a mobile phone is, for example, starting or closing Bluetooth, starting or closing WIFI, and so on. A specific operation is not limited in this embodiment.

With the triggering method provided in the embodiment of the present invention, a wireless handheld device detects an input combination that is of a click frequency and/or click intensity and is received when a touchscreen is in a locked state, and when it is detected that the received input combination of the click frequency and/or the click intensity matches a pre-stored input combination of a click frequency and/or click intensity, where the pre-stored input combination of the click frequency and/or the click intensity is corresponding to an operation, executes the operation corresponding to the matched pre-stored input combination of the click frequency and/or the click intensity. In this way, a related operation is executed according to a click frequency and/or click intensity, and it no longer needs to perform precise touch input on a virtual keyboard or a virtual button of a touchscreen. Therefore, even in a dark environment or in case of emergency, effective touch input can still be performed on a wireless handheld device whose touchscreen is in a locked state, so that it is greatly convenient for a user of a touch apparatus.

A touchscreen triggering method provided in another embodiment of the present invention is described by taking that a user starts a music player of a mobile phone whose touchscreen is in a locked state as an example.

The user may preset and store a combination of a click frequency and click intensity, where the combination of the click frequency and the click intensity is corresponding to an operation such as “starting a music player”.

For example, the user starts a touch learning function of the mobile phone. It is assumed that “three successive clicks are performed on the screen with the intensity of each click being medium” is set as an instruction combination for starting the music player. Then, after the user successively clicks a specified position of the screen three times with the intensity of each click being medium and selects “saving”, the mobile phone pre-stores the combination of a click frequency and/or click intensity for starting the music player.

In addition, before a mobile phone leaves the factory, a manufacturer may pre-store a set combination of a click frequency and/or click intensity in the mobile phone, where the set combination of the click frequency and/or the click intensity is corresponding to a related operation (such as starting a music player). After that, a user learns and memorizes the combination in a manner of animations and text in a specification or mobile phone.

It should be noted that, in this embodiment, the user clicks a specified position of the screen when storing a touch instruction. However, in an actual application, for a mobile phone whose touchscreen is in a locked state, “three successive clicks on the screen with the intensity of each click being medium” may be performed at any position of the touchscreen. A touch position during actual input is not limited in this embodiment. That is, an input combination of a click frequency and/or click intensity may be performed at preset one or more positions, alternatively, an input combination of a click frequency and/or click intensity may be performed at any one or more positions.

It should be noted that, a pre-stored click frequency corresponding to the operation may be one or more numerical intervals, and pre-stored touchscreen clicking intensity corresponding to the operation may be one or more numerical intervals. That is, a set click frequency and set click intensity for clicking the touchscreen may be one or more numerical intervals rather than one or more very precise numerical values. For example, the set click frequency is not a precise interval such as 0.5 seconds, but may be set to an interval less than 1 second. If the click intensity needs to be set, the click intensity may be set to two levels, namely, “strong” and “weak”, or three levels, namely, “strong”, “medium”, and “weak”. Setting the click frequency and the click intensity for clicking the touchscreen to numerical intervals may increase a probability of matching and identification, so that a touch input success rate of a user is larger, and it is convenient for the user to use.

When the user needs to play music by starting a music player in a mobile phone, the user only needs to perform “three successive clicks with the intensity of each click being medium”, and then the music player may be started to play music.

For example, the user may perform click in any region of a touchscreen. As shown in FIG. 2, the user may perform three successive clicks at any position of a touchscreen 20, such as a position 1, with the intensity of each click being medium. Then, a background matches the input combination with a pre-stored combination of a click frequency and click intensity. If the matching succeeds, the music player corresponding to the input combination is started to play music.

In addition, the user may perform click in different regions of the touchscreen. As shown in FIG. 3, the user performs three clicks at any three positions of the touchscreen 20, such as positions 2, 3, and 4, with the intensity of each click being medium. Then, the background matches the input combination with the pre-stored combination of the click frequency and click intensity. If the matching succeeds, the music player corresponding to the input combination is started to play music.

That is to say, no requirement may be imposed on a position where the user clicks the touchscreen, which is different from a case in the prior art that the user has to touch a specified position. In a dark ambient environment or in a case of emergency, a related operation can be performed quickly and a success rate is larger.

In addition, in this embodiment, starting the music player is taken as an example for description, however, this embodiment is not limited thereto, and other operations may also be performed, such as any one of the following, including starting one or more application programs, pausing one or more application programs, closing one or more application programs, starting one or more menus, closing one or more menus, unlocking a touchscreen, entering one or more function interfaces, exiting one or more function interfaces, setting a parameter of a mobile phone, setting a mode of a mobile phone, setting a function of a mobile phone, and so on.

With the triggering method provided in the embodiment of the present invention, a wireless handheld device detects an input combination that is of a click frequency and/or click intensity and is received when a touchscreen is in a locked state, and when it is detected that the received input combination of the click frequency and/or the click intensity matches a pre-stored input combination of a click frequency and/or click intensity, where the pre-stored input combination of the click frequency and/or the click intensity is corresponding to an operation, executes the operation corresponding to the matched pre-stored input combination of the click frequency and/or the click intensity. In this way, a related operation is executed according to a click frequency and/or click intensity, and it no longer needs to perform precise touch input on a virtual keyboard or a virtual button of a touchscreen. Therefore, even in a dark environment or in case of emergency, effective touch input can still be performed on a wireless handheld device whose touchscreen is in a locked state, so that it is greatly convenient for a user of the wireless handheld device.

In addition, the setting of touch input may be setting only a click frequency, or setting only click intensity, or setting both a click frequency and click intensity as described in this embodiment. Setting, inputting, and matching steps in a case that only a click frequency or click intensity is set are similar to those in this embodiment, which are described herein again.

As shown in FIG. 4, a wireless handheld device 40 provided in an embodiment of the present invention includes a touchscreen 401, configured to receive a click operation, a detecting unit 402, configured to detect an input combination that is of a click frequency and/or click intensity and is received when the touchscreen 401 is in a locked state, a determining unit 403, configured to determine whether the input combination that is of the click frequency and/or the click intensity, is received when the touchscreen 401 is in the locked state, and is detected by the detecting unit 402 matches a pre-stored input combination of a click frequency and/or click intensity, where the pre-stored input combination of the click frequency and/or the click intensity is corresponding to an operation, and an executing unit 404, configured to, when the determining unit 403 determines that the matching succeeds, execute the operation corresponding to the pre-stored input combination that is of the click frequency and/or the click intensity and is matched by the determining unit 403.

In this way, a related operation is executed according to a click frequency and/or click intensity, and it no longer needs to perform precise touch input on a virtual keyboard or a virtual button of a touchscreen. Therefore, even in a dark environment or in a case of emergency, effective touch input can still be performed on a wireless handheld device whose touchscreen is in a locked state, so that it is greatly convenient for a user of a touch apparatus.
